The Radeon R7 240 will be much (approximately 66%) better at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 5800 (66%)

Pixel Rate

The Radeon R7 240 is much (about 33%) faster with regards to FSAA than the GeForce 9500 GT 1GB GDDR3, and should be able to handle higher screen resolutions better. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 1440 (33%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
